- The data supports modeling and design of long-span beamless floor systems.

## Abstract

This article presents the dataset from experimental investigations on cross-laminated timber (CLT) concrete composite (TCC) floor systems. The data was collected at the University of Northern British Columbia, BC, Canada, for project-specific design decisions for “Limberlost Place”, a mass timber building for George Brown College, in Toronto, Canada designed by Fast + Epp, Vancouver, BC, Canada. The TCC systems comprised of 245 mm thick, 7-ply CLT panels with 150 mm concrete topping. A total of 18 small-scale shear connections, and 24 half-scale (4.6 m long) and 9 full-scale (9.2 m long) floors were tested. The dataset provides information on the effective bending stiffness and load-carrying capacity of long span beamless CLT-concrete floor systems. This data will also serve as essential inputs for engineers and researchers in modelling and design processes.
